Certified by ASME and equipped with a leak-proof silicon O-ring, it ensures reliable pressure relief up to 150 PSI and flow rates of 58 SCFM. Designed for high-temperature use up to 250°F, this compact valve is ideal for professional-grade air compressors and industrial applications, delivering peace of mind with every use. ## Description This Control Devices SV-150 ASME safety valve has a brass body, a 150 psi relief pressure, a 1/4" male NPT threaded inlet connection, and a stainless steel pull ring for manual pressure relief. The valve's brass body, brass valve seat, and the zinc plated steel spring resist corrosion and can be used in operating temperatures up to 250 degrees F. The preset relief pressure is accurate to within +/- 3 percent and a silicon O-ring provides a leak-proof seal to within +/- 10 percent of the relief pressure. This safety valve is American Society of Mechanical Engineers (ASME) safety rated and displays the UV mark for pressure vessel safety valves. It also displays the NB mark for certification in accordance with NB-501, National Board Certification of Pressure Relief Devices. This safety valve has a 58 Standard Cubic Feet per Minute (SCFM) flow rate and is suitable for low capacity pressure relief applications such as in home construction air compressors. Relief valves remove excess pressure or vacuum from a system. The valve openings allow fluids or gases to escape to decrease pressure, and then close once the valve reaches the reseating pressure limit. They also relieve excess vacuum by opening to release a gas into the system and then closing after it reaches its low-pressure limit. Some relief valves have an adjustment mechanism to set the pressure where the valve opens, making it suitable for various applications. Relief valves are rated according to the volume of liquid or gas that can flow through them and the material that the valve is constructed from must be suitable for the fluid or gas, which may be corrosive or at an extreme temperature, in which it operates. Relief valves are used in a variety of applications, such as air compressors, petrochemical and chemical manufacturing, natural gas processing, and power generation. Review: Fits and works great - Fits and works great Review: Seems good. - Replaced a leaking pressure relief valve. This was in the right pressure range and seems to be in the ballpark, though haven’t really tested it. Good so far, but haven’t had a runaway yet. ## Features - PLEASE NOTE: 1/4" MALE NPT THREADED INLET CONNECTION APPROX 0.54 INCHES OUTSIDE DIAMETER - Brass construction and stainless steel spring for corrosion resistance. The preset relief pressure is accurate to within +/- 3 percent and a silicon O-ring provides a leak-proof seal to within +/- 10 percent of the relief pressure. - 250 degrees F maximum temperature for use in high temperature applications - ASME safety rated with UV and NB marks ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01G2FFB5A | | Batteries Included? | No | | Batteries Required? | No | | Best Sellers Rank | #7,662 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #1 in Relief Valves | | Brand | ALL Tool Depot | | Customer Reviews | 4.6 4.6 out of 5 stars (1,314) | | Date First Available | May 23, 2016 | | Exterior Finish | Brass, Stainless Steel | | Inlet Connection Size | 0.25 Inches | | Inlet Connection Type | MNPT | | Is Discontinued By Manufacturer | No | | Item Package Quantity | 1 | | Item Weight | 0.95 ounces | | Item dimensions L x W x H | 0.5 x 2 x 0.5 inches | | Item model number | AX-SV-SERIES | | Manufacturer | All Tool Depot | | Material | Brass | | Maximum Operating Pressure | 150 Pound per Square Inch | | Number of Ports | 1 | | Outlet Connection Size | 0.25 Inches | | Outlet Connection Type | MNPT | | Part Number | SV-150 | | Product Dimensions | 0.5 x 2 x 0.5 inches | | Size | SV-150 | | Specification Met | ASME B16.34 | | Usage | Professional | ## Product Details - **Brand:** ALL Tool Depot - **Exterior Finish:** Brass, Stainless Steel - **Inlet Connection Size:** 0.25 Inches - **Inlet Connection Type:** MNPT - **Item dimensions L x W x H:** 0.5 x 2 x 0.5 inches - **Material:** Brass - **Maximum Operating Pressure:** 150 Pound per Square Inch - **Number of Ports:** 1 - **Outlet Connection Size:** 0.25 Inches - **Outlet Connection Type:** MNPT ## Images ![New 1/4" NPT 150 PSI 58 SCFM Air Compressor Relief Pressure Safety Valve, Tank Pop Off - Image 1](https://m.media-amazon.com/images/I/51k6mPZ+u0L.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Fits and works great *by B***H on January 15, 2026* Fits and works great ### ⭐⭐⭐⭐⭐ Seems good. *by M***S on December 7, 2025* Replaced a leaking pressure relief valve.
